[R] formula format for parameter estimation

[Wayne Delport]

Hello, I am trying to input the following formula into R for parameter 
estimation. I don't quite have the just of formula syntax. I understand 
simple basic regression (y ~ x), but how do I do the ff:

y = ( b0*x )/(x + b1),

where b0 and b1 are parameters that need to be solved. Any 
help/suggestions for a newbie would be much appreciated. thanks ./w
